C++分步实现职工管理系统详解

2024-11-03 来源：个人技术集锦

1.职工管理系统的需求

本教程主要利用C++实现一个职工管理系统

公司职工分类：普通员工，经理，老板，显示信息时，需要显示职工的编号，职工姓名，职工岗位，以及职责。

普通员工的职责：完成经理交给的任务。

经理职责：完成老板交给的任务，并下发任务给员工。

老板职责:管理公司所有事物。

程序功能
退出管理程序退出当前管理系统
增加职工信息实现批量添加职工功能，将信息录入到文件中，职工信息为：职工编号，姓名，部门编号
显示职工信息显示公司内部所有职工信息
删除离职职工按照编号删除指定的职工
修改职工信息按照职工的编号或者职工的姓名查找相关的人员信息
按照编号排序按照职工编号，进行排序，排序规则由用户指定
清空所有文档清空文件中记录的所有职工信息

2.功能实现

2.1创建管理类

class Worker_Manger
{
public:
	Worker_Manger();
	 //展示菜单
	void Dispaly() ;
	 //退出系统
	 void ExitSystem();
	 //记录职工的人数
	 int M_EmpNum=0;
	 //职工数组指针
	 Worker ** M_EmpArray=0;
	 //添加职工
	 void Add_Emp();
	 //判断是否编号重复,姓名可能相同
	 bool If_Id_Repeat(int id);
	 //保存文件
	 void Save();
	 //判断文件是否为空
	 bool M_FileEmpty=0;
	 //统计文件中的人数
	 int Get_EmpNum();
	 //初始化员工
	 void init_Emp();
	 //显示职工
	 void Show_Emp();
	 //删除职工
	 void Delete_Emp();
	 //判断是否存在要查找的职工
	 int IsExit_Id(int id);//Id查找方式
	 int IsExit_Name(string name);//Name查找方式
	 string IsExit_Id_Name_choice(int cho);
	 //查找联系人
	 void Find_Emp_Name();
	 void Find_Emp_Id();
	 void Find_Emp();
	 //修改职工信息
	 void Modify();
     //编号排序
	 void Sort_Emp();
	 //清空操作
	 void Clean_File();
	 //析构函数
	~Worker_Manger();
};

2.2退出功能

void Worker_Manger::ExitSystem()
{
	cout << "欢迎下次使用" << endl;
	system("pause");
	exit(0);
}

2.3增加联系人信息

oid Worker_Manger::Add_Emp()
{
cout << "请输入添加的职工数量：" << endl;
int addnum = 0;//保存用户的输入数量
cin >> addnum;
if (addnum > 0)
{
	int newSize = this->M_EmpNum + addnum;//新空间人数=原来的人数+新增加人数
	//开辟新空间
	Worker ** newspace = new Worker * [newSize+4];
	//拷贝原来空间的数据
	if (this->M_EmpArray != NULL)
	{
		for (int i = 0; i < this->M_EmpNum;i++)
		{
			newspace[i] = this->M_EmpArray[i];
		}
	}
	//添加新数据
	for (int i = 0; i < addnum; i++)
	{
		int id;//职工编号
		string name;//职工的姓名
		int dSelect;//部门选择
		cout << "请输入第" << i + 1 << "个职工编号：" << endl;
		cin >>id;
		//If_Id_Repeat(id);
		while (If_Id_Repeat(id))
		{
			int cho = IsExit_Id(id);//Id查找方式
			cout << "通讯录已经有相同的编号，请重新输入" << endl;
			this->M_EmpArray[cho]->Showinformation();

			cin >> id;
		}
		cout << "请输入第" << i + 1 << "个职工姓名：" << endl;
		cin >> name;
		cout << "请选择该职工的岗位：" << endl;
		cout << "1.职员" << endl;
		cout << "2.经理" << endl;
		cout << "3.总裁" << endl;
		cin >> dSelect;
		Worker* worker = NULL;
		switch (dSelect)
		{
		case 1:
			worker = new Employee(id, name, 1);
			break;
		case 2:
			worker = new Manager(id, name, 2);
			break;
		case 3:
			worker = new Boss(id, name, 3);
			break;
		default:
			break;
		}
		//将创建职工职责，保存到数组中
		newspace[this->M_EmpNum + i] = worker;
	}
	//释放空间
	delete[] this->M_EmpArray;
	//更改新空间的指向
	this->M_EmpArray = newspace;
	//更新新空间的人数
	this->M_EmpNum = newSize;
	//更新职工不为空的情况标志
	this->M_FileEmpty = false;
	//提示添加成功
	cout << "成功添加" << addnum << "名新职工" << endl;
	//保存数据
	this->Save();
}
else
{
	cout << "输入有误" << endl;
}
system("pause");
system("cls");
}

2.4显示职工信息

void Worker_Manger::Show_Emp()
{
	//判断文件是否为空
	if (this->M_FileEmpty)
	{
		cout << "文件不存在或文件为空!" << endl;
	}
	else
	{
		for (int i = 0; i < M_EmpNum; i++)
		{
			//利用多态
			this->M_EmpArray[i]->Showinformation();
		}
	}
	//按任意键清屏
	system("pause");
	system("cls");
	//Name查找方式
int Worker_Manger::IsExit_Name(string name)
{
	int index = -1;
	for (int i = 0; i < this->M_EmpNum; i++)
	{
		if (this->M_EmpArray[i]->M_name == name)
		{
			//找到
			index = i;
			break;
		}
	}
	return index;
}
//Id查找方式
int Worker_Manger::IsExit_Id(int id)
{
	int index = -1;
	for (int i = 0; i < this->M_EmpNum; i++)
	{
		if (this->M_EmpArray[i]->M_id == id)
		{
		 //找到
			index = i;
			break;
		}
	}
	return index;
}
}

2.5删除离职职工

void Worker_Manger::Delete_Emp()
{
	if (this->M_FileEmpty)
	{
		cout << "文件不存在或者为空" << endl;
	}
	else 
	{
		int choose=0;
		cout << "请选择通过方式几查找要删除的联系人" << endl;
		cout << "1.通过姓名查找要删除的联系人" << endl;
		cout << "2.通过编号查找要删除的联系人" << endl;
		cin >> choose;
		switch (choose)
		{
		case 1: 
		{
			cout << "请输入要删除职工的姓名" << endl;
			string name;
			cin >> name;
			int index = this->IsExit_Name(name);
			if (index != -1)
			{
				string ch = IsExit_Id_Name_choice(index);
				if (ch == "是")
				{
					for (int i = index; i < this->M_EmpNum - 1; i++)
					{
						this->M_EmpArray[i] = this->M_EmpArray[i + 1];
					}
					this->M_EmpNum--;
					//数据同步更新文件当中
					this->Save();
					cout << "删除成功!" << endl;
				}
				else
				{
					cout << "取消成功" << endl;
					break;
				}
			}
			else
			{
				cout << "未找到此人，删除失败!" << endl;
				break;
			}
		}
		case 2:
		{
			cout << "请输入要删除职工的编号" << endl;
			int id=0;
			cin >>id;
			int index=this->IsExit_Id(id);
			if (index != -1)
			{
					string ch= IsExit_Id_Name_choice(index);
					if (ch == "是")
					{
						for (int i = index; i < this->M_EmpNum - 1; i++)
						{
							this->M_EmpArray[i] = this->M_EmpArray[i + 1];
						}
					
						this->M_EmpNum--;
						//数据同步更新文件当中
						this->Save();
						cout << "删除成功!" << endl;
					}
					else
					{
						break;
					}
			}
			else 
			{
				cout << "未找到此人，删除失败!" << endl;
				break;
			}
		}
		}
	}
	//按照任意键返回
	system("pause");
	system("cls");
}

2.6修改职工信息

void Worker_Manger::Modify()
{
	if (this->M_FileEmpty)
	{
		cout << "文件不存在或记录为空" << endl;
    }
	else
	{
		int choose = 0;

	cout << "1.确定清空" << endl;
	cout << "2.取消清空" << endl;
	int select = 0;
	cin >> select;
	if (select == 1)
	{

		ofs.close();
		if (this->M_EmpArray != NULL)
		{
			for (int i = 0; i < this->M_EmpNum; i++)
			{
				delete this->M_EmpArray[i];
				this->M_EmpArray[i] = NULL;
		    }
			delete[]this->M_EmpArray;
			this->M_EmpNum = 0;
			this->M_EmpArray = NULL;
			this->M_FileEmpty = true;
		}

	system("pause");
	system("cls");
}
